UX mock for a tipping feature idea, using Bitcoins as a micro-transaction platform.
demo: http://www.whatnotlist.com/cointip/tip.html
If a user encounters content online (blog post, video, music, book) that is insightful or delightful, she/he can "tip" the author (~ a penny, for instance) to show appreciation.
Essentially a "Like" with a micro-payment attached.
